Delete Branch "%!s(<nil>)"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?

Short description of error
Saving a file with latest buildbots corrupt the files
Exact steps for others to reproduce the error
Here is a screenshot before the crash:

Indeed, can confirm this. The classroom scene crashes every time it stops rendering, and is about to go to compositing.
And the worst is how saving the file, even with the more stable 2.79 branch corrupts the files.
Added subscriber: @JacquesLucke
I cannot reproduce the crash.
Does the crash happen in the newest Blender 2.8 build, even when Render Samples is set to 1?
@JacquesLucke if I don't save the file (use the original directly), it just hangs forever, but no crash anymore. I still have to kill as it will take 1 core of CPU forever(waited 5minutes at 25%) just after rendering. Actually, the crash was "better" as I didn't had to kill the process myself. It seems it's due to the compositing phase?
However, the file corruption when saving still happen with this strange portal being added in the left corner of the room.
deactivating compositing deactivate the hang/crash, but strange "portal" still there anyway after saving:
Added subscriber: @lichtwerk
that "portal" seems to be the
dustbin
object...checking whats wrong with that...
dustBin
's displacement in //assets/dustBin.blend on the rim object (calledCylinder
) is making problems.I assume this is still not using the 'new' displacement node in that file (it will be there when you open that file, but that is probably because cycles adds that automatically when seeing an old file)
And when linking, this automatic insertion fails, see #54504.
However, when I save dustBin.blend from 2.8 it should be there (also the material setting is set to bump only), so this is a bit puzzling...
[also not sure if the height should be fed from a normal? -- removing that connection solves the error, but gives different result of course...]
my 2 cents for the moment...
Closed as duplicate of #54504

There's not really any corruption, just the same versioning issue as far as I can tell.
